Hi, my network have mobile users with notebooks, and they use public smtp IP address, when they out of office, without VPN ASA works well, but when they comes back in office they should change SMTP IP back to private. I know that my task could be solved via DNS service, but for some reason I should do Dnat and Snat on ASA, please answer me, Is it posible? (Because ASA have to nat and dnat on same interface Insidem and back this traffic to Inside again
)Please see this picture, I draw my task there. Thanks!
